Electronic Ballast
for Gas-Discharge Lamps EVG 2300
EVG 2300-S
EVG 2300-T
Functional description
Electronic, controllable AC ballast (EVG) for gas-discharge lamps of a nominal power from
500 W to 2300 W
Control of the lamp power via a galvanically separate analogue input DC 0...10V or DC
4...20mA
It is possible to operate nearly all types of mercury vapour medium-pressure lamps and metal
halide lamps the electrical characteristics of which are in the wide operating range of unit
Ignitor is switched OFF after 10 s
State of operation is indicated by light-emitting diodes
In case of fault, a potential-free change-over contact is actuated
In case of lamp faults, the output voltage is switched OFF
Optional RS232 interface to parameterize the maximum output power and to read out an
extended data range of EVG
Advantages
Lamp power can be adjusted steplessly
Lamp power can be controlled constantly over the whole mains voltage range from 196 - 255
V
Lamp power can be pulsed
Any mains voltage variations are compensated
Smaller and lighter than comparable standard ballasts
Lamp voltage and current are of square-wave type
Compensation is not necessary

Lamp nominal voltage:
100V to 300V
Parameterizable nominal power:
500W...2300W
Protection against short circuit and overload in the lamp circuit
Protection against line-to-earth fault in the lamp circuit
Warning: Protection against line-to-earth faults is no personal protection!!
No-load test
Warning: In the no-load case, voltages of up to 420 V may occur at the lamp output!!

Forced cooling
In order to guarantee the maximum power output of the EVG, it is important to efficiently cool the
unit. The cooling effect depends on the air volume flowing through the heat sink and the air
temperature. To reach the full power output, the ambient air temperature may not be higher than
50°C.
Warning: The casing may reach a temperature of up to 80°C!!
